if the middle point of the circle is the letter O
2a.
if the middle point is the letter O
answer: LOM is a central angle
central angle means it comes from the center and each part of it is a radius
central angle is the same degree as the degrees of its arc
so it would also be 84 degrees
2b.
answer: points LM make a minor arc because its less than 180
2c
answer: points LKN make a semi circle
2d
answer: LKNM is a major arc because its more than 180
2e
LKM = 360 - 84 = 276
answer: 276
2f
84*2=168 -> 360-168 = 192 -> 192 divided by 2 is 96
answer: LK is 96
2g
answer: MN is 96
2h
NK is like LM so its 84
answer: 84
2i
LKN is 84+ 96 = 180
answer: 180
2j
360-96 = 264
answer: 264
